Yes. Duracool is about 10% more efficient than R-12. R-134a is about 10% less efficient than R-12.
I have been using Duracool for over 10 years. You don’t have to drain or flush any components. It is good to put in a new receiver/drier. That is also a filter and your old one might be partially clogged.

>> Yes, but you'll need to drain the oil out of the compressor and flush the system, then add the proper amount of oil that is compatible with the 134-A

>> A better option for some of us has been to charge with Dura-Cool or Frosty-Cool. Both are a CR12-a propane/butane mix refrigerant that is widely used
